Power is transferred from you to the pedal, to the crank-arm, to the chain-ring, to the chain, to the rear cog and to the wheel. To do this, the spindle (crank spindle/bottom- bracket spindle) must be held rigidly in place and yet, allow the cranks to turn as friction free as possible. That is the job of the bearings.


You seem to be assuming that "power has to be transferred to the bearings". That is not the case. There is no "interlock". All that needs to happen is that the crank spindle can spin with low friction. As you pointed out, the inside of the bearings is smooth and so is the spindle. I guess it's possible that they slip relative to each other, but so what -- ...


I would recommend doing two things: Reassemble the hub with the thickest grease you can find (within reason). It might slow you down a little, but it will help the bearings last as long as possible. Make a mark on the back side of the cone that corresponds to where the damage is. When you're putting the wheel on, rotate the axle so that the damaged side of ...
